Sidebar isn't in my page

So I have:

<div id="content"> <!-- main content-->
  <div id="contentLeft"><!-- posts and such -->
  <!-- LOOP STUFF HERE, EDITED FOR BREVITY-->
  </div>
  <div id="contentRight">
  <!-- Sidebar call here in php -->
  </div>
</div>

But for some reason when the page loads the sidebar is outside of everything, below all of the page elements. It isn’t like this on any other page – they all work fine – just the blog page. What on earth is going on?

https://destinywayministry.com/blog <- page I’m having trouble with.

ED: On the blog page, the source looks like this:

<div id="content">
  <div id="contentLeft">
   <!-- blog loop shtuff -->
  </div>
 </div> <!-- end main content -->
 <div id="contentRight">
  <!-- sidebar call after page content?!?!? -->
 </div>
